Hello all. Please forgive me if this is covered officially somewhere, but my google-fu has been unable to help me find much recent information. I have a couple of devices (RTL SDR&#39;s) that require USB 2.0, but the pass through seems to only support a virtual 1.1 hub for devices. The devices are correctly recognized and configured by the hypervisor host, but when connected to a VM, they show up on a 1.1 hub, and the driver fails to load as a result. <div><br></div><div>I have found some older information that only USB 1.1 devices were supported via USB pass through. I haven&#39;t found much newer information, though, and also couldn&#39;t find newer problem reports.<br><div><br></div><div>I&#39;m running 4.1, upgraded from a 4.0 installation, on Centos 7. </div><div><br></div><div>I was hoping to build a little RF capture and analysis cluster using several of these devices, but this is a bit of a roadblock! Any ideas?</div><div><br></div><div>Jonathan</div></div><div dir="ltr">-- <br></div><div data-smartmail="gmail_signature">Sent from my Commodore64</div>
